This Is Why Aeroplane Windows Are Rounded
飛機舷窗為何是圓形的
By Mollie Goodfellow
文/莫麗·古德費勒
While not everyone will have pondered the subject while staring out of the window during a flight, the question as to why aeroplanes have circular windows rather than square ones is interesting.
在飛行過程中,許多人都喜歡眺望窗外,欣賞云海。但并非每個人都會思索這樣一個問題,那就是,為什么舷窗是圓形的而不是方形的。這個問題很有趣。
Over the years, aerospace engineering has made huge leaps in aeroplane technology, meaning planes can carry more passengers and go faster. The planes have also changed shape to increase safety – including the windows.
多年來,航空航天工程在飛機技術(shù)上已經(jīng)取得了長足的進展,這意味著飛機不僅在搭載人數(shù)上有所增加,而且在飛行速度上也有所提高。同時,為了提高飛機的安全性,飛機在外形上也做出了相應(yīng)的改變。舷窗,便是變化之一。
In the 1950s, when jetliners were starting to become mainstream, the De Havilland Comet[1] came into fashion. With a pressurised cabin, it was able to go higher and faster than other aircraft.
20世紀50年代,噴氣式客機開始成為主流,德·哈維蘭“彗星”客機便是當(dāng)時的主要機型。增壓座艙的誕生使得噴氣式飛機可以比其他飛機飛得更高更快。
[1] 德·哈維蘭“彗星”客機,由英國哈維蘭公司研發(fā),于1949年出廠的噴氣民航客機,是世界上第一種以噴氣發(fā)動機為動力的民航客機。
However, the plane had square windows and in 1953 two planes fell apart in the air, killing 56 people in total.
然而,該機型舷窗是方形的,1953年,該機型兩架客機在空中解體墜毀,共造成56人死亡。
The reason for the crashes? The windows.
悲劇發(fā)生的原因是什么?答案是:舷窗。
Where there’s a corner, there’s a weak spot. Windows, having four corners, have four potential weak spots, making them likely to crash under stress – such as air pressure.
哪里有拐角,哪里就有弱點。方形舷窗有四個角,就有著四個潛在的薄弱點,使它們很可能在大氣壓等壓力作用下破裂。
By curving the window, the stress that would eventually crack the window corner is distributed and the likelihood of it breaking is reduced.
因此,讓窗緣線條彎曲,來分散窗口四角的壓力,從而大大降低了窗戶破碎的可能性。
